Audio denoising is the pre-step in the audio processing,and wavelet domain denoising has been a main research area.In order to give people a summary knowledge of wavelet domain audio denoising,based on many literatures,this paper attempts to make a survey of wavelet domain audio denoising.First,it introduces wavelet transformation and the characteristics,and gives the optimal selecting and dealing criterion of wavelet domain denoising,the basis wavelet selection.Second,describes five classical methods of audio denoising,for example,threshold,multi-wavelet,wavelet packet,modulus maximum and scale correlation,then introduces their development.Third,introduces a new algorithm based on modulus maximum and scale trading theory.At the end,the future trend of wavelet domain audio denoising is pointed out.

音频降噪是音频处理前期的必要步骤，小波域降噪是其中一个重要的研究方向，为了使人们对小波域音频降噪有概括了解，在对小波域音频降噪相关文献进行分析和理解的前提下，首先介绍了小波变换及其特性，同时阐述了小波降噪的最优选取和处理准则，及对音频进行小波变换时小波基的选取原则；然后评述了用于音频降噪的阈值，多小波、小波包、模极大值和尺度相关法等5类方法及各自的发展；接着介绍在前人基础上，提出新的基于模极大值和尺度理论的降噪算法；最后探讨了小波域音频降噪的发展方向。

Results show that in recent years, the summer rainfall in Harbin displayed the most apparent cyclical variation on a 29-38-year scale, the largest modulus, and the strongest energy; and the summer rainfall in Nenjiang did an obvious cyclical variation on a 19-30-year scale, and its energy value is quite large. Both the two cyclical variations showed a trend of being stronger in energy with the time.

结果表明：哈尔滨近年来夏季降雨在29~38a尺度周期变化最明显，模值最大，能量最强；嫩江夏季降雨在19~30a周期变化较强，能量值较大；2个周期变化都具有随时间推移能量进一步加大的趋势。

Accurate control and fabrication of silicon surface structures from atomic scale to micrometer scale,which may be randomly associated with surface roughness or have well defined patterns,is critical for the per-formance and reliability of electronic devices.

从原子水平到微米尺寸，准确控制硅表面结构的精密加工，诸如无序的表面粗糙或者精细的图案，乃是电子元件性能及其可靠性的保证。

Micro-scale effect and multi-field coupling are characteristics of the design of micro-electro-mechanical system. However, the current macroscopic structure-oriented CAD systems have not been able to meet the increasing requirements for the design in micrometer scale. Therefore, a flexible design modeling methodology for MEMS based on Petri net is put forward.

微机电系统设计具有微尺度效应和多物理场耦合的特点，而现有的面向产品宏观结构的CAD系统难以满足微米尺度设计需求，为此提出一种基于Petri网的MEMS柔性设计建模方法。
